摘要
抽水蓄能机组在电网低谷负荷时作抽水负荷,降低火电机组的压火损耗;电网高峰负荷时顶替火电机组出力调峰。但目前国内对抽水蓄能电站的节煤效益进行定量模拟计算研究尚较少。为此,根据安徽电网年负荷曲线实际资料,模拟计算、分析抽水蓄能电站的运行工况和燃料成本,得出在电网中适当建设抽水蓄能电站具有节煤效益的结论。
The pumped-storage generating unit pumps water at low load of power grid to decrease the loss of thermal generators, and modulate the load at the peak load of power grid. But there is a little research on quantitative analysis of coal saving benefit of pumped storage power plants in our country today. According to the year load curve of Anhui province, this paper simulates calculating and analyzing the working status of pumped storage power plants and the cost of fuels, and has got the conclusions of that we can get coal saving benefit by building pumped storage power plant in power grid properly.
